Specific implementation mode
Here illustrative embodiments will be illustrated in detail, the example is illustrated in the accompanying drawings.Following description relates to
And when attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary is implemented
Embodiment described in mode does not represent all implementations consistent with this disclosure.On the contrary, they be only with such as
The example of the consistent structure of some aspects be described in detail in the appended claims, the disclosure.
In the disclosure, the use of noun of locality "front", "rear" is the habituation definition according to corresponding parts use state, tool
Body refers to the front and back of mobile terminal, referring to figure 6 and figure 7, before the top of page is, after lower section is；"inner", "outside" are typically
For profile of corresponding parts itself.In addition, the term " first " that the disclosure uses, " second " do not indicate that it is any suitable
Sequence or importance, but for distinguishing an element and another element.
Fig. 1 and Fig. 2 schematically illustrates the mobile terminal shell of disclosure offer and the knot of mobile terminal rear cover respectively
Structure.As shown, rear cover 10 includes backboard 11 and the riser 12 extended forward from the edge of backboard 11, riser 12 is around backboard 11
Periphery setting, the parts such as battery can be accommodated wherein forming accommodating chamber by being formed as the circumferential side wall of mobile terminal, be stood
The installation via of volume key, power key and charging socket etc. can be offered in the plate face of plate 12.Referring to Figure 1 and Figure 3, riser
Chamfering 121 is formed on the inside of 12 front end face, mobile terminal front housing 20 is equipped with buckle 30, the madial wall of the riser 12 of rear cover 10
Face is equipped with clamping portion, for locking buckle 30.With reference to Fig. 6, before clamping, 30 are buckled in the raw, in riser 12
There is certain amount of interference between side wall surface；When clamping, buckle 30 moves backward, and end is after contacting riser 12 by riser 12
It presses and inwardly (i.e. the right side of page) retraction, in this course, buckle 30 is supported first in chamfering 121, is being fallen
Under the guiding role at angle 121, buckle 30 can be slided backward swimmingly, since buckle 30 is contacted when being caught in chamfering 121, no
It can be cut scaling-off, to avoid influencing its installation strength, also avoid causing installation accuracy difference and cause to remove and do over again.
Clamping portion can be the baffle protruded from the interior sidewall surface of riser 12, and in this case, buckle 30 moves backward,
The rear end of baffle is locked on after baffle；Clamping portion may be from the recessed holding tank of the interior sidewall surface of riser 12, at this
In the case of kind, after 30 movement in place of buckle, it can extend into holding tank.
In embodiment of the present disclosure, as shown in Figure 6 and Figure 7, clamping portion is from the recessed appearance of the interior sidewall surface of riser 12
Receive slot 40, the shape of holding tank 40 can be with the Contour matching of buckle 30.Further, the interior sidewall surface of riser 12 is formed
Have towards the recessed direction of holding tank 40 and tilt the guiding surface 122 extended, before guiding surface 122 extends to holding tank 40
End.By taking Fig. 6 as an example, guiding surface 122 is located at holding tank 40 in the top of page, when being pressed the buckle 30 of retraction along vertical
When the interior sidewall surface of plate 12 moves backward, elasticity is supported in the interior sidewall surface always, after 30 contact guiding surface 122 of buckle,
It is gradually directed to the release of inclined-plane 122, until reaching 40 position of holding tank, buckle 30 extend into holding tank 40.In this way, due to
Buckle 30 is gradually discharged, and can be impacted holding tank 40 suddenly to avoid it, be caused impact failure.
The size of chamfering 121 can be designed according to the wall thickness and height of riser 12, the wall thickness of width and riser 12 it
Than that can be 1:4-1:7, on the one hand when the width of chamfering 121 is excessive, it is unfavorable for end face and other parts of riser 12
Cooperation, on the other hand when the width of chamfering 121 is too small, function and effect unobvious are easy to cause the incised wound buckle of riser 12
30.Since the rear cover wall thickness of the mobile terminals such as mobile phone or tablet computer is usually 0.6mm-0.8mm, in this case, chamfering
121 width can be 0.1mm-0.2mm, and correspondingly, the height of chamfering 121 is approximate with its width, or
0.1mm-0.2mm.It should be noted that the direction of the wall thickness of the width direction and riser 12 of chamfering 121 can refer to Fig. 6 and
The left and right directions of Fig. 7 drawings, the height of chamfering 121 can refer to the upper and lower directions of Fig. 6 and Fig. 7 drawings.
As shown in Figure 1, Figure 2 and Figure 4, the side of front housing 20 has been positioned apart from multiple buckles 30, correspondingly, riser
Also multiple clamping portions have been positioned apart from 12, to be corresponded with multiple buckles 30, so as to reinforce front housing 20 and rear cover
10 connective stability.
The disclosure is not limited the concrete shape of chamfering 121, for example, can be arc surface or can be and riser 12
End face relative tilt plane, need to only ensure that buckle 30 when touching riser 12 backward, contacts i.e. with chamfering 121 first
It can.In order to reinforcing chamfer 121 to buckle 30 guiding role, guide frame can also be formed with by buckling 30 end, for
Chamfering 121 coordinates.For example, in an embodiment of the disclosure, with reference to Fig. 3, chamfering 121 includes before being formed in riser 12
The first inclined-plane between end face and the interior sidewall surface of riser 12 forms to slide with the first inclined-plane on buckle 30 and match with reference to Fig. 5
The second inclined-plane 31 closed.Further, the angle between the first inclined-plane and the front end face of riser 12 is less than or equal to the second inclined-plane
Angle between 31 and the rear end face of buckle 30, that is, in Fig. 6, the angle of the first inclined-plane and horizontal direction is less than or equal to second
The angle on inclined-plane and horizontal direction.In this way, when buckling 30 close to riser 12, the rear end and first on the second inclined-plane 31 is ensured always
Inclined-plane contacts first, to reinforce the guiding role on the first inclined-plane.
Technical solution in aforementioned embodiments based on the disclosure, it is also proposed that a kind of mobile terminal, the mobile terminal are matched
It is equipped with above-mentioned mobile terminal shell, and the beneficial effect with above-mentioned mobile terminal rear cover and mobile terminal shell whole
Fruit, details are not described herein again.In the disclosure, mobile terminal can be mobile phone, tablet computer or music player etc..
Those skilled in the art will readily occur to other embodiment party of the disclosure after considering specification and putting into practice the disclosure
Case.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or adaptability
Variation follows the general principles of this disclosure and includes the undocumented common knowledge in the art of the disclosure or usual skill
Art means.Specification and embodiments are considered only as illustratively, and the true scope and spirit of the disclosure are wanted by following right
It asks and points out.
It should be understood that the present disclosure is not limited to the precise structures that have been described above and shown in the drawings, and
And various modifications and changes may be made without departing from the scope thereof.The scope of the present disclosure is only limited by the accompanying claims.
